The 2013 calc is:
$240/sh * 118mm shares = $28.4B market cap, less $746mm cash, plus $576mm debt = $28.2B TEV
The 2019 calc is:
$204/share * 173mm shares = $35.3B market cap, less $2.2B cash, plus $11.2B debt = $44.3B TEV
For those mentioning subtracting the debt, that's incorrect. A company is capitalized with equity and debt. To buy the whole company, you have to buy both. But when you buy the equity, you get the cash, so you subtract that out, since buying cash isn't relevant. You then have to add the debt, because you have to pay off all the debt to own the company outright.
Because according to the comment above debt is 11B, and I happen to know that they have ~2B cash on hand, so roughly speaking enterprise value should be 9B larger than market cap right now, and it should have been less than 600M above market cap back then (their old debt value also listed in a comment above).
Rather, market capitalisation reflects investor’s assessment of the enterprise value.
Whether rational or not, this already takes cash and debt positions into account.
